Washers
Spring and lock washers in the grade you need
HAGUE FASTENERS makes spring washers in the UK in any material you require, from non-standard mild steel sizes to duplex and nickel alloys. If it is not a standard stocked, mass-produced washer, we can make it.
Split spring washers, curved and wave washers and conical spring washers keep tension in a joint. Matching the washer material to the bolt avoids galvanic corrosion in marine and chemical service.
Where they are used
- Electrical and busbar connections
- Machinery and equipment
- Marine and offshore fittings
- Joints with thermal cycling
- Matching corrosion resistant bolting

Questions
Frequently asked questions
What does a spring washer do?
A spring washer keeps some tension in a bolted joint as it settles. On its own it is not a reliable locking device for vibration, so critical joints often use lock nuts instead.
What is the difference between DIN 127 and DIN 6796?
DIN 127 covers split spring washers. DIN 6796 covers conical spring washers for bolted joints.
Can you make spring washers in Inconel or super duplex?
Yes. We make spring washers in nickel alloys, duplex and stainless steels to match the rest of the joint.
Is there a minimum order quantity?
No. We make single prototypes and urgent breakdown replacements as well as batches of several hundred.
